Application mea February 2s, 1920. seriai No. 361,974.

T0 all whom t may concern Y Be it known that I, IRA D. BRILL, a citizen of the United States, residing at Marlington, 1n the county of Pocahontas and State of West Virginia, have invented a new and useful Lock, of which the following is a specification. n

The device forming the subject matter of this application is a lock, and .oneV object of the invention isto provide a structureV of the sort alluded to which may be mounted readily in a door or 4other barrier, it being necessary merely to bore ahole in the edge oi the door, and to bore a hole transversely through the door. l The invention aims to provide a lock which may be manipulatedreadily from the inside of the door, through the instrumentality of a knob, it being possible to manipulate the device from the outside of the door, by means ot a knob, only after a key has been insertedinto the outside knob.

Av furtherl object of the invention is to provide a lockwhich will be compact in construction, embodying but few parts.

The invention aims to provide novelmeans `for moving the locking bolt.

It is within the province of the disclosure 'to improve generally, andr to enhance the utility of devices of that type to which the invention appertains. w

WV ith the above and other objects in view, which will appearl as the description proceeds,` the inventionr residesin the combination and arrangement olf-parts and in the details of construction hereinafter described and claimed, it beingunderstood that, within the scope of what is claimed, changes in the `precise embodiment of' the invention showncan be made Without departingfrom the spirit of the invention. I

ln the accompanying drawings Figure 1 is a horizontal section, taken through a door wherein the device-'forming the subject matter of this application has been mounted, parts appearing in elevation; Fig.'2 is a verticalzsection taken approximately on'the line 2-2 of Fig. 1, parts having beenleft in elevation; l Fig. B is a cross section taken through the casing of the lock, on the line 3-.3 of Fig. 2;'Fig.` 4 is a fragmental vertical section taken ontheline 4-4 of Fig. 3, parts being inelevation; Fig. 5 is a transverse section taken on the line 55 of Fig. 4; Fig. 6 'is ,a cross section on the line 6-6 'of Fig. 1; and Fig. 7 isa crosssection on the line 7-7 of Figl.

The numeral 1V denotesV a barrier of `any sort, such as a door, a recess 2 being formed `in the free edge ofthe door. This recess 2 ordinarily is f fashioned by boring a hole With an auger or like tool intheedge of the the .door 1, thereby forming side openings 3 which 'communicatewith the recess 2. From 'the' foregoing it will be obvious that, so V:tar

as preparing. the door for the reception of the lock is concerned, It is necessary merely to bore one auger hole into the'edge'of theV Adoor `1` and yto borek another auger hole through the door from side to side.

' Atubular casing 4 isinounted 'in the recess 2 land is held in place by arplate co-y yof vthe manufacturer may demand. l The tubular casing 4 isprovided, as* shown best in Fig.1, with side-openings 6, alined with the side openings 3`fin' the doorl.

including 'a diskV 7-'secured within the casing v4 immediately in the rear of the side open- Vingsf, the frame including a disk 8 disposed immediately in 'rontof the openings 6, a disk 9 being ysecured in the casing 4 between vdoor 1. Aftransverse hole is bored through 1 `v A frame is fixedwithin the tubular casing p 4, the frame being av composite-structure and' they disk'8 and the outerendof the casing. Y

For convenience in claiming the invention, or In describing it .briefly hereinafter, the

disks 7, 8 and 9 may be alluded vto as supports. Rods 10 extend-longitudinally of the I casing-4 and rconnect the disks' or supports 9 and 8. g T hedisks 8 and 7.r are connected by similar rods 11. Y Y

e The numeral 12 designates generally, a locking `bolt embodying va 'head 14 mounted to slide in the plate 5 and fitting closely but slidably inthe forward vend ot the casing 4, f

the head `having a rearwardly projecting tubular stem V15 mounted toreciprocate in the forward disk 9. @The rear end` of aY `line in Figl, is' secured tol the-'rear endlof the tubularstem v15. `ofthe locking boltf12` spindle 1G isv secured to theintermediate disk K `v 1.5 of the lockingy bolt 12 being l 19 of the' c'rossrhead 17. l edges, the slides 20 are shaped, as shown at y 22 in 1F ig. 3, to cooperate with theinnersurface of the tubular casing 4in..such a way and is disposed behind the disk 9, the cross head being provided viii its ends with notches or openings 19, the function of which Will be made manifest hereinafter. Av compression spring 18 surrounds a portion of the spindle 16, the rear end of the spring abutting against the disk 8, thek forward end of the spring abutting against the cross head 17, or, at least, against the rear `end of the tubular stein 15 of the locking bolt 12. Recalling that the frame comprising thev disks 9 and 3 is fixed'vvithin'the tubular kcasing'4,

itwill be clearthat the springy 18V tends to .advance the lockingbolt V12 until the cross Vhead` 17 engages the forward disk 9, the

parts beingshown thus arranged in Fig.1

- ofthe drawing.A

The numeral 2() denotes a pair of slides located within the casing 4 and diametri- -cally opposite to each other, the slides'being -in the forin of bars having racks 21 ontheir inner edges, intermediate the ends of the slides. The slides are mountedl for right line reciprocation in the edges of-the disks 7 and 3, the slides being received in the notches Upon their outer that the slidescannot rotate upon their axes. Consequently, the racks 21 always project inwardly. Since the slides 20 are received in the notches 19 of the cross head 17, the cross head cannot tilt and the locking bolt 12 cannot rotate on its aXis, the bevel 100 of the @head 14 of the'- locking boltv being kept always in such a position that it'will exercise its function when the door.1 is swung to a closed position. The forwardv ends yof the slides 20 are supplied with lateralY lugs r23, shown'best'in Figs; 3 and 4. Thereare openings 24 (see Fig. 3) in the forward disk 9, the openings being so shaped `and being large enough, so that the lugs 23v can vpass therethrough, when the sidesV 20 are drawn `rearwardly. The lugs 23, having. passed through theopenings 24 'in the forward disk 9, cooperate with the cross head 17, so as 'to draw therross head and the locking bolt 12 rearwardly, thereby compressing the spring 18, it being observed atthispoint, referring to F ig. 5, lthat thenotches 19 in the ,cross head 17 are not large enough to permit the lugs 23 to pass therethrough when the slides 20 aref drawn rearwardly,'a comparison of Vthenotches 19A of Fig-5 with the openings 24 of Fig. 3beingprolitable at this point.

',The rearend Vof 'the head 14f1of the locking when .the slides are advanced.l Y Y It has been lpointed out hereinbefore that bolt 12 maybe cut awayasV shown at'25', so

as to receive the lugs 23'on the .slides 20,

a Aright linereciprocationis imparted to the slides 20, the means'for imparting this re ciprocation to thesl'ides embodyinga pinion the knob 35' thus spindle 33.

grooves 41.

26 located within the casing 4 and engaging` the racks 21 of the slides 20, as shown in Fig. 2 of the drawings. The pinion 26 is 'carried 'by 'a shaft 27 kinounted to rotate in Va face plate 28, secured to the inner side of Ythe door 1, the inner end of the shaft 27 being provided with aknob 29.

InY that side of the pinion26 which is re- Y mote from the knob 29, a Circular opening` 39 is fashioned, there being lateral seats 31 in Vthe pinion, thev seats lcommunieating with the opening 30, these details appearing to best advantage in Fig. 2. A face plate 32 is attached to theouter side ofthe door 1, a tubular spindle 33 being fixed to the plate. VVThe numeral 34 denotesthe baseof a .knob

35, the base of the knob havingv a tubular neck 36. The outer end of the tubularspinvdle 33 isreduced as shown at 37, so vas telit within the neck 36 of the'knob Screws 38.- or-like securingA devices are niounted'in the neck 36 of the-knob 35, the inner endsV Vof vthe screws-being.received ina shallow VcircuinseribingV groove 50 formed Von rthe outer surface of the reduced partV 37 ofthe tubular spindle 33. It will beobvious that is mountedto rotate on the The numeral 39 designates a-,shaft located within the tubular spindle 33, the inner end of the shaft-extending through one of the side openings 3 of the door 1 andthrough the corresponding openingl 6V ofthe tubular Vcasing 4, the inner end of the shaft 39 being freely rotatable in the opening 30 (see Fig. 2) which is fashioned-in one side ofthe pinion 26. Vllheouter endl ofthe shaft 39 is supplied with a transverse` head 40 received in grooves 41 fashioned in theneck 36 .of the knob 35, the'reduced part 37 ofthe spindle 33 serving to hold the head 40-in vthe It will now -be obvious that when rotation `is limparted to the knob735,

:the shaft 39 will be rotated also, but, so far as the device has been-described up to this point, the shaft 39-will not. impart rotation to the pinion 26 because the inner end of the shaft 39 is free to rotate infthe opening 30 in the side of the pinion. A slot or opening :42' is formed in the head 40l of the shaft 39 shape to the slot 42 'in the`transverse head 40 of the shaft 39. The numeral n44 denotes a key,.the shank ofy whichv maybe inserted -throughthe slot 43 throughthe slot 42, and

longitudinally Vofthe shafty 39,`betw'een` the I parts 45 thereof, Vthe inner end of the key 44 being received in the lateral.seats 31 of the 'pinion 26 (see Fig. 'When the key 44 is mounted in placeas above described,

the shaft 3) is coupled to the pinion 26 so that when rotation is imparted to the shaft, rotation will be imparted to the pinion, the pinion coperating with the racks 21 to operate the slides 20,0ne slide being retracted when the other slide is advanced, depending upon the direction in which the knob 35 is rotated. To' the base 34 of the knob 35, a

shell 46 is hinged as shown at 47. The shell' 46 carries a resilient latch 48, the head 49 of which is adapted to coperate with a projection 50 on the base 34 of the knob 35, to hold the shell 46 in closed position. One

end of a spring tongue 51is secured to the base 34 of the knob 35, the other end of the tongue engaging the head 49v of the latch 48,

thetongue including a button 52 projecting outwardly through the base 34 of the knob. When the spring tongue 51 is pushed inwardly by pressure applied to the button 52, the head 49' of the latch 48 is disengaged from the projection 50 and then the shell 46 may be swung to an open position on the hinge 47 .Y

y InA practical operation, a person standing,V on the indoor side of thedoor 1 may rotate the shaft 27 through the instrumentality of the knob 29. Since the shaft 27 is permanently connected to the pinion 26, the door may bc opened out the use of a key, the pinion coperating with the racks 21 of the slides 20, to retract the projections `on that'slide 20 which has been advanced.

When the cross head is drawn rearwardly, y

the bolt 12 is drawn rearwardly, because the cross head is attached to the rear end of the stem 15 of the bolt, the spring 18 be ing compressed. Obviously, when the bolt' 12 is retracted,'the door 1 may be opened. When the knob 29 is released, the spring 18 reacts on the cross head 17 and advances the same until. the cross head engages the disk 9, the bolt 12 being advanced.

Passing now tothe condition which eX- ists when a person standing on the outside of the door 1 desires to operate the bolt 12,

it may be statedv that Vif the keyv 44 is not in place, the knob 35 may be rotated without actuating the piniony 26l and without retracting the bolt 12, since from the inside with- When one of the slides 20l the inner end of the shaft 39 is freely rotatable in the opening 30 in the vside of the pinion 26. When, however, the key 44 is in place, as above described, the inner end of the key is received j in the seats 31 of thepinion 26. Then, if the knob 35 is rotated, the pinion 26 will be rotated, and the slides 20 will be operated,

' theibolt 12 being retracted. If desired, the

shell 36 of the knob 35 may be swung to an open position and thel key 44 kmay be withdrawn, or, if desired, the key 44,1nay

' be left in place, as shownin Fig. 1 of thel drawings, under which circumstances, the knob 35 will'remain operatively coupled to the pinion 26.v
